(eCl. 5221-94) Y Zl Claims.

This invention relates to a soap dispensing device- Itis an objectl of this invention to provide a soap dispenser which may be operated without touching thevdevice with the hands and without danger of leakage.

It is a further object to provide a dispenser of the character described which will dispense the soap at the `levellof the hands from a container on the oor by foot action but which, nevertheless, will insure the prompt delivery of soap Withont-dripping or clogging and without the presence ofbulky apparatus at the level of the body.

The invention accordingly comprises the feature of construction, combination of elements, andarrangements of parts, whichwill be exempli fied in the construction hereinafter set forth and the Ascope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention, reference` should be had to vthe following detailed description, taken in connection with the accompanying drawings, in which:

Figure 1 isa centrallongitudinal section of an apparatus embodying this invention.

. Figure 2 is a top plan View of the same.

Figure 3 is a side elevation of a modified form of the device.

AFigures 4 and 5 and6 are details of the device of Figure 3.

Figure -'l is a section through the pumping mechanism.

Figure 8 is a vertical section through the head construction of Figure 1.

As shown in Figure 1, the device comprises primarily a base I within which is carried a soap container I I adapted to be filled through an opening I2 closed by a cap I3. A vertical hollow post I5 extends upwardly from the base I9 to the height at which it is desired to dispense the soap and on the top of this post is mounted an arm I6 which is rotatable about the axis of the post.

A cylinder 20 is mounted on the base Il] in position to extend into the soap container I I and substantially to the bottom thereof. Slidable within this cylinder is a piston 2l carrying upon' its lower end an expansible Washer 22 which is held in place by a screw 23.A A spring 24 urges the piston upwardly. The piston has at its upper end an annular channel 25 terminating in an integral collar 26 and above the collar is a further reduced end 21 for operating the piston. A

rubber button 28 at the top of the end 2l reduces 55 nut noise in its contact between the piston, and the operating lever to be described.

A washer 29 surrounds the upper lend 21 of the piston. This washer is held between the upper end of the cylinder 2li-and a cap nut 30 which at thesrame time screws down upon the outside of the portion 25 of the cylinder to hold the latter inplace and alsol holds the washer 9A in place to limit the up stroke of the piston by engagement between the washer and the collar 26. A rubber buiger SVI is inserted in the top of the nut 3 0 to prevent noise if the operating lever should strike the top of the nut. Holes 32 are provided inthe top ofthe cylinder 20 within the soap dispenser inV position to permit anysoap which creeps beyond the Washer 22 into the channel 25 to be discharged back into the container.

The cylinder 20 has anr opening 33 in its bottom normally closed by a ball valve 34. This ball is held in place by a suitable cage 35 carried by the spring 24,.

In the side of the cylinder there is screwed a nipple 35 carrying a ball valve 3S pressed toward the cylinder 20Yby a spring 3l so that the valve 34 permits the soap solution to pass into the cylinder 20 on the upstroke of the piston 2| and the valve 36 permits it to pass through the nipple 35 on the downstroke of the valve.

Attached to the nipple 35 is a coupling 38 for the purpose of facilitating` the assembly of the device. This coupling is connected to the arm I6 byatube 379 carried within the post I5.

The hollow post I5 is preferably screwed into the base I0 as shown at 40 and may be provided with a hollow sleeve 4I surrounding the lower portion of the base. Into the top of the post I5 there is screwed an annular member 42 into which the upper end of the tube 39 is also screwed as shown at 39a so that the tube is firmly supported by the post.

The arm I6 is carried by a head 43 having a depending nipple 44 terminating at its upper end in a shoulder 45. An annular bearing member 46 surrounds the nipple 44 which engages and bears against the shoulder 45. This bearing member 46 is screwed into the top of the post I5 and thus furnishes a bearing support for the head 43. The bearing member 43 has an internal recess 4l in its bottom and within its recess a washer 48 is held by an annular nut 49, thus furnishing a bearing surface against the bottom of the recess 4l which prevents the removal of the head 43 when the bearing member 46 is screwed into the post I5. The bottom surface of the 49 engages a packing Washer 50 to make a soap tight joint and the nut 49 has a pair of holes for the purpose of turning the nut upon the nipple 44.

A lever 52 is hinged to the base I0 at 53 and has a foot treadle 54 so arranged as to be substantially at the iioor level when the piston 20 is at the bottom of its stroke and to rest above the floor level only so far as is necessary to allow the piston to make its full upward stroke so that the treadle 54 may be easily depressed by raising the toe without taking the Weight off the heel.

In the form of the invention disclosed in Figure 3 the base I0 and the dispensing arm I6a are connected by a flexible tube 55 connected at 56 with a Monel metal tube 51, but these are not housed within a posi'l such as l5 but are carried by suitable supports as for example by cleats 58 attached to the wall. In this embodiment the arm I6a is provided with a downwardly extending head 59 having a reduced portion 60 fitting within an opening 6I in stud 62 supported upon the wall by any suitable mechanism such as that described in my co-pending application Serial #236,880, filed October 25, 1938.

This reduced portion 6E! is provided with openings 63 which communicate with an annular recess 64 within the stud 62 which in turn communicates with the tube 51 by means of a bore 65.

In the form of the invention disclosed in Figure 4 the tube 51 connects the soap tank, not shown in this figure, with :the dispenser arms I6b which is swiveled as shown at 12 with the same construction as that shown in Figure 1. In this figure, however, the arm l6b and head 431) are not supported by a post extending from the tank but are carried by suitable supporting means from the wash basin itself.

As shown there is provided a conical washer 14 bearing at its lower end against the wash basin and having its upper end supporting a, flange 15 upon the upper end of a stub post 16 which, insofar as the swivel is concerned, performs the same function as the post l5 of Figure 1. This post 16, however, is short, extending only far enough below the wash basin to receive the nut 11 to hold the parts in place.

Since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
